In-situ soil nutrient concentration based facility crop fertilization method and system

Abstract

The invention relates to the technical field of facility agriculture and provides an in-situ soil nutrient concentration based facility crop fertilization method and system. The facility crop fertilization method includes: S1, setting a soil nutrient content supply target value according to a facility crop type; S2, acquiring in-situ soil solution in preset depth of a soil layer in a cultivation region, and testing the nutrient content in in-situ soil; S3, collecting actual water content of in-situ soil in the preset depth, and calculating irrigation amount and nutrient content of irrigation water; S4, calculating fertilization nutrient supply amount. The method and the system have advantages that the facility crop fertilization nutrient supply amount can be acquired conveniently, and nutrient supply amount of different types of facility crops can be quickly determined without soil damage, and accordingly blindness in fertilization is avoided, concentration stability of nutrients in soil is guaranteed, and timely and accurate supply of nutrients in a facility crop growing process is realized.

Description

technical field [0001] The invention relates to the technical field of facility agriculture, in particular to a method and system for fertilizing facility crops based on in-situ soil nutrient concentration. Background technique [0002] Facility agriculture is a high-input, high-output, capital-, technology- and labor-intensive industry. It is the only way for traditional agriculture to gradually get rid of the shackles of nature by using artificially built facilities and move towards modern factory agricultural production. An efficient way to consume demand. For facility crops widely planted in facility agriculture, facility crops grow fast, have high yields, and require a large amount of nutrients. It is difficult to meet the needs of crop growth and development only by relying on nutrients in the soil. Fertilization is an important technical link in the production of protected crops, and it is also an important supplement to the nutrient requirements in the growth proce...
